'Ihis invention relates particularly to the mounting of reflectorbuttons in sign plates or boards of natural or artiiicial wood or likefibrous material which can be readily pierced with a sharp instrument.

Inaccordance with this invention the button employed has a limitingcircumferential flange or collar near its front end and the button bodyis of a size to'enter a hole bored in the face of the mounting until theflange or collar strikes the outer face of the mounting. The body isprovided however, with protuberances such as sharp barbs, for example,which extend beyond the wall of the hole and pierce the material. As thebutton is forced in by pressure against its outer end,

the protuberances bite into or pierce the wall and secure the button inthe hole.

When barbs are used hey wili preferably be inclined to the axis so as ohave a spiral disposition and thus cause the button to rotate as it isforced into the hole, the barbs describing a spiral path in the wall.Preliminarily the wall will preferably be treated to seal the pores andexclude moisture. The barbs will most convenient- 1y be formed on aseparate clip applied to the button.

I shall now describe the illustrated embodiment Y Fig. 1 is a crosssection through a button ren ceiving hole in a sign board mounting witha button shown in place and with a mounting tool immediately above thebutton.

Fig. 2 is a plan of the barb carrying clip shown applied to the buttonin Figure 1.

Fig. 3 is a side elevation of the clip.

Fig. 4 isa view similar to Figure 1 showing a slightly modied form ofmounting.

In the form of mounting shown in Figure l, the board 1 has a cylindricalhole 2 bored therein, of a size to receive the body of the button 3 witha fairly tight iit: The hole is first treated with shellac or paint toseal the pores of the wood and keep out moisture. The iiange 3a on thefront end of the button is of a. size to abut against the vfront face ofthe mounting and thus provide an overlap to seal the opening.

At the bottom of the cylindrical wall of the button body are providedtwo diametrically 'opposite securing lugs 3b and 3c. On these there issecured the clip 4 shown in detail in Figures 2 and 3. This clip is ofsheet metal and has a bottom plate portion 4a with arcuate ends andupstanding from the ends are the arcuate flanges '55 AMaand 4c, one ateach end. These flanges are 1933, Serial No.'685,428

provided with ahole or recess which receives and interlccks with therespective securing lug 3b or 3c. Thus the clip is locked on to theb'ody.-

One corner of each flange 4b and 4c is bent back to form a barb, the twobarbs being formed on corresponding corners of the flanges and beingsubstantially equally inclined to the axis of the button so as to have aspiral relation. p 'I'he barbs are numbered respectively 4b' and 4c andthey extend well beyond the wall cf the hole when the button iscentrally disposed therein. Consequently they pierce into the wood andsecurely hold the button in place against any pulling force which canordinarily be applied to the outer end o of the button.

To insert the button a tool 5 such as shown in Figure 1 may be used.This has a socket of a size and shape to receive the end of the buttonwith the peripheral edge resting on the flange 3a. Mallet blows on theouter end of the tool so set will drive the button into its hole andcause the barbs to cut a path along the wall.

lSince the barbs are spirally disposed they willv traverse a spiral pathas'the button is forced longitudinally. In other words the button as awhole will rotate as it descends.

Where itis desired tol recover the button after a short period of use,the hole in the mounting should be drilled entirely through as shown at2a in Figure 4, and a back plate 1a placed over the rear of the signplate as shown. To recover the reflector the back plate is removed andthe reflector mayy be driven out from the rear with a flat faced toolwithout any injury to the reflector.

It is obvious that the construction illustrated and described can beotherwise variously modiiled without departing from the spirit or scopeof the invention as expressed in the appended.
